Calculate earth's average speed relative to the sun.

Average speed of the earth relative to the sun = 30045.17 m/s

Explanation:

To calculate the average speed of the earth relative to the sun, we would have to divide the distance traveled from earth to sun by the time of travel. Thus;

Average speed of the earth = Distance travelled from earth to sun/total time of travel.

Now, formula for distance traveled by earth = 2πr

Where r is the average distance from the Earth to the sun and is given by 1.508 × 10^(11) m

Thus;

distance traveled by earth = 2π × 1.508 × 10^(11) = 947504344322.6816 m

Total time is time taken for the earth to complete a revolution around the sun. Time = 365 days

Converting this to seconds gives;

Since 24 hours make a day, we have;

365 × 24 × 60 × 60 = 3.1536 × 10^(7) s

Thus;

Average speed of the earth = 947504344322.6816/(3.1536 × 10^(7)) = 30045.17 m/s
